FIELDS

       PID    process ID

       CMD    process name

       SYSCALL
	      system call name

       COUNT  number of system calls made in this sample

DOCUMENTATION

       See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
       bose descriptions explaining the output.

EXIT

       syscallbypid.d will sample until Ctrl-C is hit.
